  • Only cat food that my cat will eat.

    By on

    My cat is 10 years old. When I got her from the Humane Society, she was very small. She was 4 months old before she reached the weight requirement for adoption. After I brought her home, she had diarrhea. I started her on Science Diet Sensitive Stomach and her diarrhea resolved. I kept her on the Sensitive Stomach formula for a few years, then switched to Optimal Care, which she tolerated well. I tried other brands of cat food; i.e., grain-free, and she wouldn't eat any other brand of cat food but Science Diet. I've tried to give her chicken and tuna in the past as a treat - she wouldn't eat it. I've never had a cat like her; she will only eat Science Diet.

  • Cats like it so far

    By on

    I have two kitties who are brother & sister. They are one & a half years old. I adopted them from a cat rescue place less than a month ago. They was feeding all their cats Science Diet so I thought I would try that too. So far they seem to like this particular one okay. They don't prefer it over the canned which I feed them during the day...but eat it in between the canned food feedings and mostly at night. I have always fed my kitties a larger amount canned cat food than dry but this one looks to be a fairly high quality for dry cat food. They prefer it to a less expensive brand that I bought at first.

  • Three paws up

    By on

    3 cats of all different sizes & ages & this works for everyone-- best of all they all like it & come running when the bowl is filled. I believe it also had the highest percent of protein too. We've tryed others in the science hill brand but this was the favorite & didn't cause upset tummies. The only con is the food is little small bits (think pencil erasers) & greed eaters try to take mouthfuls causing it to scatter all over the floor.

    Not sure why, but my two cats tolerate most cat food but love Hill's - can't say why!? I've bought high dollar foods and always go back to Science Diet.

    My six cats like this much better than SciDi Indoor, which they'd been getting. We'll see how the new food affects the litter box. Indoor was great at reducing litter box odor.

    my two kittens just turned a year old so I switched them from the kitten formula to Adult & at first they didn't seem to care for it ( bigger pieces) , but after the first week they seem to be doing fine with it.

  • Dry cat food is great

    By on

    Our 1 year old cat loves this food! It doesn't smell at all either in the bag or when out in her bowl. We've been buying this food for about 8 months and wouldn't pick out anything else!

  • Kitty loves it!

    By on

    Very happy with this food. We adopted a 1yo male cat who we had been feeding friskies indoor food. After a few weeks he started having diarrhea and littler box problems. I switched to this and after the first few days I saw major improvements! No more little box problems. Also he is not going through food as fast as he was before. Even though this brand is pricy compared to store brands, it's worth it for a happy healthy kitty!
